Engadget has gotten hold of a video which shows someone applying a reasonable amount of downwards pressure on the phone's back, and just look how much it gives. According to the source, you have to supply a "reasonable amount of force" to replicate the results, so it's unlikely to happen in everyday use. But just look at it!

It's also probably worth pointing out that this is a pretty dumb way to treat your electronic devices. But then, hopefully you already knew that. [Engadget]
